"Hehe, sister, I didn't know you were busy."

After saying that, Lin Qiye took three or two steps to Lin Jiuyue's side.

"Sister, didn't you say that you were going to extract the penicillin liquid today? I came over to take a look."

Lin Jiuyue rolled her eyes when she heard this.

"Still watching! If I weren't your sister, I'd be so steady and scared by you. Not only would I not be able to extract penicillin, I'd also have knocked over this earthenware jar."

Hearing this, Lin Qiye felt even more embarrassed.

"Sister, I didn't mean it. Don't blame me, don't blame me."

"By the way, sister, where are you at?"

Lin Qiye came forward and watched Lin Jiuyue carefully scoop out the contents of the earthen jar.

"After scooping out, use carbon powder to absorb the remaining liquid, then wash the carbon with distilled water, then add acidic water, and finally alkaline water. The remaining liquid can be filtered once with a cotton funnel."

“I just don’t know if it will succeed.”

My production steps are correct, but I don’t know if I can succeed.

After listening to this, Lin Qiye frowned.

"Huh? There are so many steps involved? I thought it would be done in no time."

Lin Jiuyue rolled her eyes when she heard this.

If penicillin was really that easy to make, people would have developed it long ago. Why would they have waited until now?

"You think making penicillin is as easy as cooking?"

Lin Qiye: ...

Well, I was scolded by my sister again.

At this moment, Gu Chengyan also came over.

"September, Qiye said you were going to extract penicillin today, so I came over to take a look."

As he spoke, Gu Cheng had already walked to Lin Jiuyue's side. Looking at the thick layer of oil in the wooden basin next to Lin Jiuyue, he asked curiously.

"Hey, Jiuyue, what's in that basin? It looks like unsolidified oil to me."

This stuff looks like oil, but on this day, oil solidifies quickly. Could it be vegetable oil?

“It’s canola oil.”

After listening to this, Gu Chengyan frowned and thought about it.

Rapeseed oil? Isn't that the rapeseed that was planted in September? How could it be harvested so soon? If I remember correctly, the rapeseed she planted isn't ready for harvest yet, right?

"Is your rapeseed ready to be harvested?"

After hearing this, Lin Jiuyue realized that she had said the wrong thing.

"No, these are rapeseeds I collected while fleeing the famine. I squeezed out the oil from them. There wasn't much in total, so I didn't want to eat them. Now they come in handy."

Lin Jiuyue didn't know whether Gu Chengyan would believe her explanation.

But now that things have come to this, I can’t think of any better explanation than this.

Gu Chengyan had previously fled to the capital with Lin Jiuyue and the others, and he knew that Lin Jiuyue always collected some strange plant seeds along the way. However, he had never expected that Lin Jiuyue would actually collect so many rapeseeds.

"I see. I thought your rapeseed had already been harvested."

After hearing what Gu Chengyan said, Lin Jiuyue finally breathed a sigh of relief.

As of now, the oil issue has probably been concealed.

"Haha, rapeseed can't be harvested until around May next year."

While Lin Jiuyue was speaking, his hands did not stop moving.

After only the bottom layer of liquid remained, Lin Jiuyue followed the steps and added the charcoal powder that had been prepared in advance. After absorbing the liquid, she washed the charcoal with distilled water.

Seeing Lin Jiuyue's serious expression, Gu Chengyan and Lin Qiye couldn't help but become nervous.

It was not until late at night that Lin Jiuyue stopped what he was doing.

"September, is this okay?"

Gu Chengyan looked at the liquid placed in front of Lin Jiuyue curiously.

"Okay. I just don't know if it succeeded or not."

Gu Chengyan: ...

"How do you know if it's successful?"

Hearing this, Lin Jiuyue frowned.

There are no precise instruments for analysis here, so if we want to know whether penicillin is successful, we will probably have to conduct more experiments.

It is feasible to conduct experiments on animals, but the reactions of animals are more or less different from those of humans.

Besides, even if penicillin is successfully produced, it still needs to be tested on the skin. Some people are allergic to penicillin, and severe cases can be life-threatening. Only people who are not allergic should use this medicine.

“Without precise instrumental analysis, we can only slowly experiment.”

"What do you need? I'll get it ready."

When Gu Chengyan heard that there were still experiments to be done, he became a little anxious.

The medicine has already been made. It would be a real pity if it gets stuck at this last step.

"No, I'll prepare it myself. But you can find me some mice."

Lin Jiuyue still couldn't bear to conduct experiments on humans.

"That's easy, just wait."

In order to find out as soon as possible whether penicillin was successfully produced, Gu Chengyan turned around and ran to find the experimental mice without saying a word.

Lin Qiye stood aside and felt a gust of wind passing by him, and then Gu Chengyan disappeared.

"So fast?"

After saying that, he turned and looked at Lin Jiuyue.

"Sister, how confident are you about this penicillin?"

Lin Jiuyue stretched out her hand and gestured.

"Ninety percent? That high? When did you learn how to make penicillin?"

A smile appeared on Lin Jiuyue's lips.

"Of course, when you don't know."

In the 21st century, with the development of the internet, we can now learn to make not only penicillin but also ancient imperial secret medicines. However, the effectiveness of these medicines remains unknown.

Lin Qiye: ...

Gu Chengyan, who was eager to verify whether penicillin had been successfully produced, quickly ordered people to catch the mice that Lin Jiuyue needed.

"September, look at this mouse. It's still alive and kicking."

Lin Jiuyue glanced sideways at the mouse in Gu Chengyan's hand.

"Can."

Lin Jiuyue fed some penicillin liquid to the experimental mice, and then sat aside and observed quietly.

Seeing Lin Jiuyue like this, Lin Qiye and Gu Chengyan also sat beside her.

It was already very late at night, but the three of them were all focused on the mouse and no one felt sleepy.

It was not until dawn that Lin Qiye yawned.

"Sister, is it okay? Did we succeed?"

Lin Jiuyue also yawned.

"Okay, it's a success."

This penicillin should not be taken orally directly after it is produced, but there is no syringe for injection now, so we can only try to let the experimental mice take it orally.

Later, I will do some further research and improve this penicillin, and then I can make it into one that can be taken orally.

"Did it really work?"

After hearing this, Gu Chengyan showed a surprised expression on his face.
